How do you say welcome to as in Welcome to Carolina in Finnish?

Answer 1

"Tervetuloa [PLACE]+[END]."
Enter the name of the place to the [PLACE].
But the [END] is very difficult to foreigners. You have to say the right kind of syllable at the end.
These are combined like this: [VOWEL]+n (Like in this case -an). This is determined by the last or second to last letter. Sometimes it's not normal (New York = -iin).
If the place ends in a consonant, there are two vowels at the end...

So the sentence goes like follows:
Tervetuloa Carolinaan.

Foreign names can be difficult to conjugate into Finnish, because in Finnish nouns get a suffix at the end to add meaning. For example house is talo, but in the house is talossa, into the house is taloon.

This can provide for some awkward versions of foreign place names. In this case it would be most natural to pronounce Carolina like you would in English, but stretching the last "a" and adding the n.
